Sick time is a benefit that is afforded to most paralegals. Firm policies differ quite a bit regarding sick time. I once worked at a firm that gave me "unlimited" sick time. I was never really clear on what that actually meant but I was astute enough to know that it didn't mean that I call out sick one day a week and still get paid. I also know that firms don't expect you to use all of your sick time unless you are in fact sick, very sick. Some firms allow you to carry over sick time in case you become gravely ill and some pay you for your alloted days that are unused at the end of the year. The point is that everyone gets sick and you should never go to work with a fever or a highly contagious flu, thats just inconsiderate and its the reason the firm gives you sick time. Everyone needs a mental health day now and again - but you should not to use all of your sick time and sick time certainly shouldn't be used on the beach or ski slopes -- thats what vacation time is for!
The powers that be do take notice to how much sick time you use and it does reflect on you, your work ethic and your committment to your firm.
